FUEL-OIL BURNER.

Specification of Letters Patent.

Patented May 1, 1917.

Application filed August 14, 1916.v Serial No. 114,884.

To all 'whom t may concern.'

Be it lmown that l, JAMES S. GrrsoN, a citizen of the United States, residing at Fort Stockton, in the county of Fecos and State of Texas, have invented certain new and useful Improvements in Fuel-Oil Burners; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to malte and use the same.

This invention relates to yimprovements in fuel oil burners or heaters which are adapted to be placed in the fire box of any ordinary type of stove, particularly cook stoves.

The primary object of the invention is to provide a device of this character which while being simply constructed will be very efficient in operation.

An additional object is to provide a device formed of two heaters, each of which may be operated independently of the other, one being used for heating the oven, while the other is used for heating the parts of the stove above the fire box.

Still another object is to provide air inlet means whereby air is supplied to the burner openings in both parts of the device.

With these. and many other objects in view7 my invention resides in the features of construction shown in the accompanying drawings which will be later described and claimed.

In these drawings:

Figure 1 represents a longitudinal sectional view through the fire box of a stove with my improved heater disposed therein, the latter being in side elevation;

Figs. 2 and 3 are horizontal sections' taken respectively on the planes of the lines 2-2 and 3--3 of Fig. 1;

Figs. 4 and 5 are vertical transverse sections on the planes of the lines 4-4 and 5-5 of Fig. 2; l

Fig. 6 is a detail section on the plane of the line 6-6 of Fig. 3;

Fig. 7 is a transverse section on the! line 7--7 of Fig. 2; and

Fig. Sis a detail sectional view through a portion of the tubing which comprises the pipes of the heater.

Referring more particularly to the drawings the reference character F represents the fre box of a stove S, the fire box being provided with the usual grate G upon which my improved heater is designed to rest. Before the heater is placed within the fire box, however, a sheet of asbestos 1 is disposed upon a plate 1 so as to exclude air from the lire box and also to form a pan uponl which fuel oil is disposed and lighted in order to generate gas within the heater preliminary to starting the same.

This heater comprises a burner section 2 and a vaporizing section 3, the pipes of each section being disposed in substantially parl allel spaced apart planes, the lower or burner section having a plurality of sets of openings therein through which the gas generated in the upper section is liberated.

The heater is also formed in two parts 4 and 5, either of whichmay be operated independently of the other, and each of which consists of a single piece of tubing of suitable diameter, one end portion containing burner openings while the other is connected to the source ofsupply of the fuel oil. The part 4 will be termed a heater proper and has one'end extended through the front of the fire box, which is closed in a suitable manner, and is connected to any preferred form of cut-0H valve 6 through which the fuel oil from the tank (not shown) passes on 'its way to the burner. The oil before reaching the valve 6 passes through the pipe 7. The opposite end portion of this part of the heater is bent upon itself to form a loop'8, the arms 9 and 10of which are disposed substantially parallel and in the same horizontal plane as'shown in Figs. 3 and 4. The base of this loop is shown disposed at the rear end of the fire'box, and the free end thereof is extended upwardly as at 11, then continued laterally toward the rear of the fire box in a plane substantially parallel to that ofthe loop 8, and then bent upon itself to form an additional loop 12, the arms 13 and 14 of which are disposed substantially over the arms 9 and 10 of the loop 8. Both the arms 13 and 14 are disposed in the same horizontal plane which is parallel with that of the loop 8, and they form a part of the vaporizing section 3, the rest of which will be later described. The free end of the arm 14 of the loop 12 is next bent downwardly and then continued laterally toward the rear of the re box parallel to and substantially in the plane of the arms 9 and 10 of the loop 8 in order to form a burner 15 in which a plurality of sets of burner openings 16 are formed. This portion 15 is preferably arranged directly between the arms S) and 10 and has its openings 1G positioned upwardly so that the llames therefrom extend to the vaporif/iing section directly above.

rlrhe other part 5 which is termed the oven heater, alsov has one end extended through an opening in the liront of the lire box of the stove connected to a suitable cut-off valve 17 through which the fuel oil passes from the pipe 7. The opposite end portion is bent upon itself to term a loop 1S, the arni 19 oit which being the supply pipe or portion olV the member 5 which is connected to the valve 17, and the other arm 20 is positioned between and parallel to the arms 13 and lelof the loop 12 as shown in ligs. 2 and d. rfhe inner portion of the arm 19 is disposed adjacent the arm 10. r1`he free end o1 the arm 20 is bent downwardly and laterally to torni the burner portion 21 which is arranged parallel to the arms of the other loops and adjacent the arms and 19. The burner openings 22 of this portion 21 are inclined so as to throw the lames which issue therefrom toward the inner or oven wall of the lire box in order to quickly and thoroughly heat the oven.

From this description it will be seen that the burner section includes the arms 9, 10 and of the part ll and the arms 1S) and 21 .o'l the part 5, and that the vaporizing section comprises the arms 13 and 14: of the loop 12 and the arm 20 of the part 5. These two parts are eifectively held in cooperative position with respect to each other by means of the tie straps which surround the arms 13, le and 20. The pipe 7 which connects the valves (i and 17 also aids in spacing the outer end portions of the parts fr and 5 and holds them in position.

1n the present device 1 have shown two sets oi burner openings 1G, one being adjacent each end of the arm 15. Surrounding the supply pipes of the burners which are 'formed by the arms 9 and 19, are air inlet tubes and respectively, these tubes being extended 'through openings in `the front of the fire box so to permit air to cuter the interior of the latter. The inner ends of the 'tubes terminate adjacent the sets of openings 1G, the tube 2d terminating adjacent the innermost set of openings, while the tube 25 stops near the outermost set, thus supplying the needed amount or air to the directly at the point of discharge. Fingers or spiders 26 are arranged within these two tubes 24 and 25 in order to space the same 'from the supply pipe. 1t will also be noted that the tube 25`terminaites adjacent the openings 22 in the oven burner portion 21 so that air is also supplied thereto.

1n order to spread the Haines which issue from the openings 16 and direct them upon the arms 13 and 14; of the vaporizing section, 1 provide the deflecting members 27 which are in the form of asbestos sleeves bound by copper rings 28 and are disposed upon the arm 20. These deflectors are slidable upon the arm 2O so as to permit them to be disposed overthe openings 16 or not as desired. By this arrangement the intense heat from the burner section is directed upon all parts of the vaporizing section so as to evenly heat the same.

All parts of the tubing Which comprise the heater proper and also the burner heater are Iilled with a plurality of strands of wire 29 as shown in the figures on thel second sheet of drawings. 'This construetion permits the fuel oil within the tube to be very quickly vaporized when heat is applied 'thereto, since only a small quantity oi" oil can be contained therein at one time.

W ith the parts disposed in the fire box of the stove S as hereinbefore described, the burners are prepared for lighting by pouring a quantity of fuel oil upon the asbestos pan 1 and igniting the same, thus heating the parts of the burner and vaporizing the oil therein. Tvllhen this oil has become vaporized, and supposing it is desired to light both parts of the device Which include the burner openings 16 and 22, both the valves G and 17 are opened to permit the fuel oil to flow from the tank, and the gas is ignited. 4 The flames from the openings 16 will cause the oil which is continuously flowing'l from the tanlthrough the valves G and 17 to become vaporized so that it may flow from the burner openings in the form of gas, the Haines from the openings 22'also aiding in this vaporizing operation to a certain extent. Where it is only desired to heat articles upon the top of the stove over the lire box, the valve 17 is cut ol so as to stop the flow of oil to the oven heater. rlhe formation of gas Within the vaporizing section 3 continues, thereby supplying gas to the burner openings 16. When only the oven heater is desired, the4 other .valve is cut ott. 1t is obvious that it is unnecessary to start the heater pipe by lighting both parts thereof, either one may be started in the same manner independently of the other.

`While the heater is shown disposed Within the lire box of a cook stove and it is primarily designed for use in such, it is evident that with slight changes it may be used in a stove designed only Jfor heating purposes. 1n such a case the oven burner could be done avvay with or so arranged that its openings are directed upo'n the va. porizing section.
